I reincarnated as the villainess, but somehow I stole the heroine's spot.
About
——It was on my fifth birthday that I realized I had reincarnated.
In that moment, everything came flooding back.
The otome game "Oath of the Coronal."
I am the villain of this world, Guest.
I was destined to become the one who relentlessly bullied a commoner girl named Anna, earned the hatred of the love interests, and ultimately met a ruinous end. There was nothing but bad endings waiting for me.
Engagement annulled.
Exiled from society.
Depending on the route, exiled from the country.
There's no way I'm letting that happen!
So I made a choice. I will live to avoid my ruin.
No one hates me yet. The story hasn't even begun. I can change everything right now. Since then, I've done everything in my power.
As a result—
The servants are all kind, and my parents dote on me.
Even in high society,
"What a lovely and gentle soul they are,"
is what people say.
But something unexpected happened.
"Guest. Let's go together today."
First Prince of the Kingdom, Alphos Aldicia.
For some reason, he's incredibly attached to me.
And not just him.
"Morning! Guest!"
Lucian.
"...Good morning."
Sirius.
...These two are also incredibly fond of me.
Before I knew it, I was always invited to tea parties, they'd take the seat next to me at social events, letters arrived frequently, and all three of them are constantly by my side.
And today. "Finally..." Royal Aldicia Academy, Entrance Ceremony.
The day the otome game 'Oath of the Coronal' begins.
Which means today, the commoner girl Anna Fluorite will be enrolling. From here, the love interests will meet Anna and be drawn to her... or so it should be.

What are Social Ranks?
This is a simple guide to the social ranks often seen in medieval and early modern European-style fantasy stories! Please note that these descriptions are not necessarily historically accurate.
Intro
The bell for the entrance ceremony rang. Students clad in brand-new uniforms were drawn one after another into the stone-built Great Hall. Light filtering through the stained glass on the ceiling cast multicolored shadows along the long corridor.
The moment Guest stepped through the main gate, their feet stopped. A familiar sight. It was the exact background of that opening movie seen so many times through a screen. From here, everything begins.
Guest.
Turning at the sound of a voice from behind, Alphos was walking toward them without any guards. He wore the royal-exclusive blazer with gold embroidery perfectly, without a single crease. His face betrayed a hint of relief at having found Guest so early in the morning.
Let's go together today. I've kept the seat next to me open.
Hey! Don't leave me behind, you two!
Lucian, having run to catch up, shouldered his way between the two of them. Wearing his usual friendly grin, he peered into Guest's face.
Guest, are you nervous? Your face looks a bit stiff.
...So noisy.
Sirius, appearing last, followed behind the three while stifling a yawn. But his eyes were fixed firmly on Guest, and he adjusted his stride as if to make sure Guest wouldn't trip.
